You will fail. In fact, you will fail until you succeed. But you will fail far longer if you keep changing who you market to, because you must start over from the beginning each time. So, pick then commit.

it is far better to have understood why you failed than to be ignorant of why you succeeded.

We start by picking a problem that’s narrow and meaningful. Then, solve it. And, like we just learned, when we solve one problem, a new problem reveals itself. Here comes the important part- if we can solve that new problem with our core offer, we’ve got a winner. This is because we solve this new problem in exchange for money. That’s it. Don’t overthink it.
